IMPROVEMENT IN COMBINED ATMOSPHERIC EXHAUST PUMPS AND FUNNELS.

Specification forming part of Letters Patent No. l36,26 l,dated February25, 1873.

1'0 all whom it may concern:

Be it known that I, GEORGE H. RANDALL, of Forestville, in the county ofPrince Georges and State of Maryland, have invented a new and CombinedAtmospheric Exhaust Pump and Funnel; and I do hereby declare thefollowing to be a full, clear, and exact description of the same,reference being had to the accompanying drawing forming a part of thisspecification.

The invention relates generally to funnels through which liquids arepoured into vessels, but more particularly to those used with sirup,molasses, and other viscous fluids. The invention consists in makingfunnels with an external sleeve, closely joined to the funnelbody, andextending down the nozzle for a suflicient distance to enable its end toreach within the jug, demijohn, barrel, cask, or other receptacle forthe liquid, and in connecting the chamber thus formed between nozzle andsleeve with an air-exhaust pump, as hereinafter fully described andsubsequently claimed.

The figure represents a vertical section.

In the drawing, A represents an ordinary funnel having body a and nozzlea. B is asleeve, soldered to the funnel-body at b and extending down thenozzle a far enough to reach within the vessel to be filled. This formsan air-tight channel-way, 1), between the nozzle a and the sleeve B.With this channel-Way b is conjoined a neck, 0, of the air-exhaust pump0, which is preferably soldered to the funnel at two points, 0 0 D isthe piston, which is operated by a hand-rod, d.

The application is as follows: The funnel A is placed with its nozzleand sleeve within the vessel which is to be filled and the sirup orother liquid then poured into the funnel. The atmospheric pressure abovethe funnel and below the nozzle being equal gravity is the only forceused to carry the viscous liquid into the receptacle; and as this isbarely suffi cient to overcome the cohesive attraction between theparticles of the mass in the funnel the inflow is very slow and tedious.

By my invention, as soon as the funnel is filled with sirup, I exhaustthe air from vessel and thereby remove its counter-pressure, thusutilizing the outside atmosphere to force the sirnp rapidly into thereceptacle.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

The combination of an air-exhaust pump with a funnel for liquids, as andfor the purpose described.
